Ecological houses have become very popular lately due to an increasing concern regarding the reduction of the CO2 emissions generated by the building sector. An ecological house is perceived as a building that enhances the environment rather than degrading it. Straw bale houses are considered to be an ecological and energy efficient solution to the traditional houses. The research aimed to evaluate the use of straw bale in constructions. The experimental work included the mechanical and the hygrothermal behaviour of straw bale, i.e. compression test, moisture content and thermal conductivity determination on a straw bale wall placed in climatic conditions specific for Romania. The research results show a better thermal performance than some of the traditional choices existing on the market. The study provides encouraging insight into considering straw bale solutions as a first alternative to the classical ones.
